The Martian meteorite Northwest Africa (NWA) 16254 is a 406-g gabbroic shergottite found two years ago in Algeria. Image of the entire NWA 16254 sample...

An unexpected phenomenon called convection could help explain many of the volcanoes and other features of the Venusian landscape. Artist’s impression...

Fossil feathers are usually preserved as carbonaceous films and impressions in lacustrine and marine sediments, or embedded in amber, but rarely mineralized....

The newly-discovered volcanic hotspot is larger than Earth’s Lake Superior, and belches out eruptions six times the total energy of all the world’s...

Magma reservoirs beneath volcanoes along the Cascade Range arc vary in depth, size and complexity, but upper-crustal magma bodies are widespread, according...

Volcanic activity on Io — the innermost Galilean moon of Jupiter and the most volcanically active body in the Solar System — is unlikely to...

Using the ESPRESSO instrument on ESO’s Very Large Telescope and the HARPS instrument at ESO’s La Silla 3.6-m telescope, astronomers have detected a...

Io is the most volcanically active body in the Solar System. Io’s volcanoes are powered by both the extreme tides from Jupiter and the gravitational...

Using images from the JunoCam instrument aboard NASA’s Juno spacecraft, planetary scientists have spotted a fresh volcano with multiple lava flows and...

There is extensive geologic evidence of ancient volcanic activity on the Moon, but it is unclear how long that volcanism persisted. Magma fountains produce...

These bright (hot) ‘thermal rings’ are a common phenomenon, and they are indicative of active lava lakes, according to a new analysis of data from...

Using high-resolution color images from ESA’s Trace Gas Orbiter (TGO) and Mars Express missions, planetary researchers have found evidence for morning...

Using the SHARK-VIS instrument on the Large Binocular Telescope on Mount Graham in Arizona, the United States, astronomers have captured the highest resolution...

Using radar data from NASA’s Magellan mission, planetary scientists have detected volcanic-related flow features in two different regions of Venus: on...

Sulfur and chlorine isotopes in Io’s atmosphere indicate that it has been volcanically active for the entire 4.57 billion-year history of the Solar System. This...

In December 2023 and February 2024, NASA’s Juno spacecraft made extremely close flybys of Jupiter’s volcanic moon Io, getting within about 1,500 km...

Provisionally designated Noctis Mons, the newly-discovered volcano is located just south of Mars’ equator, in Eastern Noctis Labyrinthus, west of Valles...

The relatively well-preserved ancient crust of Mars provides a natural window into early planetary evolution not available on Earth. Mars has generally...

On February 3, 2024, NASA’s Juno spacecraft made a second close flyby of Io, the fifth of Jupiter’s moons and the third largest. Like the previous...

The Sturtian ‘Snowball Earth’ glaciation (717 to 661 million years ago) is regarded as the most extreme interval of icehouse climate in Earth’s history....
